We look at the division of 209851 by 38 
The aim is to understand the frequency of 38 in 209851.

Advancing to step 1:
When dividing 2 by 38, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 38

Moving on to step 2:
38 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 38

Let's proceed to step 3:
38 can be fit into 209 5 times, resulting in a remainder of 19.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 190 from 209, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 38

Going ahead to step 4:
If we divide 198 by 38, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 55.0
Subtract 190 from 198 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 38

Moving on to step 5:
38 can be fit into 85 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 552.0
Subtract 76 from 85 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 38

On to step 6:
38 can be fit into 91 2 times, resulting in a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 5522.0
Subtract 76 from 91 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
If we divide 150 by 38, we get 3 and a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 5522.3
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
38 goes into 360 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 5522.39
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
The number 38 fits into 180 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 5522.394
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
38 goes into 280 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 5522.3947
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
When dividing 140 by 38, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 5522.39473
If we subtract 114 from 140, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
The number 38 fits into 260 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 5522.394736
If we take 228 away from 260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
320 divided by 38 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 5522.3947368
If we subtract 304 from 320, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
160 divided by 38 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5522.39473684
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 5522.39473684 with a remaining 8e-09.
